Epilepsy Awareness Program - Nervous System

 

Overview

The nervous system is the most complex system of the human body and considered as a functional component. Every moment of the day your nervous system is active, and provides you the ability to perceive, understand and react to environmental events. That is why the nervous system is so extremely important for human behavior.

It exchanges millions of signals corresponding with feeling, thoughts and actions. The human brain itself consists of at least 10 billion nerve cells (or neurons) plus supporting (neuroglial) cells.
Neurons are able to respond to stimuli (such as touch, sound, light, and so on), conduct impulses, and communicate with each other (and with other types of cells like muscle cells). it is also responsible for controlling all the biological processes and movement in the body, and can also receive information and interpret it via electrical signals which are used in this nervous system. The human nervous system controls everything from breathing and producing digestive enzymes, to memory and intelligence.
It conducts stimuli from sensory receptors to the brain and spinal cord and that conducts impulses back to other parts of the body.


The nervous system is organized into three basic functional and structural categories, the central nervous system,
the autonomic nervous system, and the peripheral nervous system (the nerves that carry impulses to and from the central nervous system).

The autonomic nervous system is the key to involuntary functions such as breathing and maintaining a heart rate.

The peripheral nervous system is primarily responsible for
centralized communication which detects and sends electrical impulses that are used in the nervous system

The central nervous system (CNS) (the brain and spinal cord) is the primary nervous system with the largest communications network within the human body which is essentially the processing area which detects and sends electrical impulses that are used in the nervous system

All three segmented nervous system categories are always working in constant continuity with each other.

Nervous System Divisions

Peripheral Nervous System

  • In the PNS, collections of neurons are 
    called ganglia

 

 

 

 

Central Nervous System

 

In the CNS, collections of neurons 
are called nuclei.
